OSTEOPATHIC TABLE.

Application filed February 21', 1920. Serial No. 360,429.

To all whom it may concern:

Be it known that I ALBERT M. Fnnrsn, a citizen of the United States, and a resident ot the city and county of San Francisco,

State of California have made a'new and useful inventi-onto wit, Improvements in Osteopathic Tables; and I do herebydeclare the following to be a full, clear, concise and exact description of the same.

This invention relates particularly to improvements in chiropractic operating tables. Among the objects of the invention are to provide a range of adjustability to meetthe anatomical positions of the patient in drug less treatment methods and necessaryin accomplishing spinal and other adjustments, particularly in the chiropractic art. Another object is to render the table equally adaptable and comfortable to male and e male patients. Another object is to concentrate and arrange the control of the table, so that the operator can adjust it to the various positions with the minimum of eiiort. Other objects and advantages will appear as this description progresses.

In this specification and the annexed drawings the invention is illustrated in the "form considered to be the best, but'it is to be understood that the invention is not limited to such form, because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

In the accompanying three sheets of drawings.

Fig. 8 r is a fragmentary detail in side elevation of the dorsal support adjustment. Fig. 9 is a similar view in front elevation.

Fig. 10 is a sectional elevation illustrating the adjustment of the abdominal support.

Fig. 11 is a vertical section illustrating a modified form of adjustment for the abdominal support.

Fig. 12 is a still further modification of the abdominal support adjustment.

In detail the construction illustrated in the drawings includes the end supporting legs 1 1 and 22 connected by the side strips 3 and 4t and the end strips 5 and 6; The risers 7 and 8 are spaced inward from opposite ends of the table and rise upward from the side strips 3 and 4:. The space intermediate these risers are decked over as at 9. The opposite ends of the table are closed by the panels 1111 and'12-12 respectively. The foot of the table is further enclosed by the panel 13. v

The head portion comprises a top board .14: hinged at 16 to the riser 7 and may be adjusted as to inclination by the edge strip 17 supported by the swing bracket 18 pivoted at 19 between the legs 11 and having a portion 21 engaging and supporting the edge strip 17.

The head board 14: is provided with transverse slots. seel ig ti in which the studs 22 ot'. the cheek boards 23 and 24 are slidable to guide ,the cheek boards. These cheek boards are provided with upholstered cheek pads 26 and 27 adapted to support the face of the patient, leaving free breathing space between the cheek pads.

The chest rest 92 is'pivoted at 93 to the riser 7. and is provided with the padding 94: therein. The chestboard rests upon the dorsal board 28 and is free to follow the same inits pivotal movement. To limit the radial movement of the chest rest 92, I provide the metal arms 95 secured to the front face of the riser 7 and having thearm 96 thereof bent to a predetermined position to limit the downward radial movement of the chest rest. As will be noted the chest rest moves with the dorsal board and maintains itself in substantially planal alinement therewith.

The dorsal board 28 is pivoted at 29 to'the riser 7 and supported at its outerend by the toggle lever 29 pivoted thereto at 31.. and pivoted 32 to the toggle link 33 that is pivoted at 34 to the riser 7 beneath the deck 9 that is provided with an opening 36 to pass the toggle lever 29. The dorsal board 28 is resiliently supported by the contracting coil springs 37, the opposite ends of which are ing to the slot 43 in the end panel 13. This lever is provided with a pawl adapted to engage a series of notches 44 in the lower edge of the opening 43. The spring board 38 is connected with the lever 41 by the flexible cord 46 passing around the pulley 47 attached to the leg 2 whereby the arcuate movement of the lever adjusts the distance between the spring board 38 and the toggle link 33 to vary the tension of the springs 37. In Fig. the dorsal board is shown in an abnormally depressed position as it is normallysupported by the tension of the spring 37 and is normally depressed by the chiropractor bearing down against the spine of the patient. The dorsal board 28 is fixed in the horizontal position by the stop 48 adaptdorsal boa'rd and free at its opposite ends to few ed tobe slid under the end of the link 33 by the handle 49 projecting through a slot in the deck 9 within convenient reach of the chiropractor. r

A limited manualadjustment is provided in the length of the toggle lever 29, see Figs.

8 and 9, by the plate 51 of the pivotal hinge 31 being provided with a slot 52 through which the threaded bolt 53 passes. This bolt passes through a hole in the lever 29 and is provided with the threaded handle 54 bearing against the plate 56 whereby the dorsal board may be adjusted by clamping the plate 51 against the lever 29 in any desired posit'i'on by means of the screw handle 54 within convenient reach of the chiropractor.

The dorsal board 28 is provided with a transverse board 57 fixed thereto and providedfwith the upholstered pad 58. This pad has a novel feature in the flexible corners 59 that are depressed below the plane of the pad 58 to which they are flexibly connected at 61 and are supported by the fieiiible strip 62 fixed to the underside of the resiliently support the breast pads 59. This feature is obviously designed for the com- 1 liditandprotection for female patients.

""The foot o fthe table is provided with the thigh" supporting pad"63 resting upon the board 64'fixedacross the end of the table. The abdominal support board 66 is slidably guided beneath the board 64 through'sldts in then-ser- -8 and the rear abdominal board67. The front end of this board rests upon the anti-friction roller 68 mounted'on the riser 81 The board 66 is mani ulated by means of the; lever 69 pivoted at $1 to the side panel 12 and protrudes through a slot in the panel 12 on the opposite side. i This lever and the board 66 are inter-connected by the link 72' pivoted 'theretoat 7 3 and 74; wherebythe ar'cua'te movement of the lever is trans;

formed into a longitudinal movement of the board 66. The protruding end of the board is provided with the upholstered pad 78. By this arrangement the weight of the patient resting abdominally on the pad 78 and supported on the anti-friction roller 68 may be moved longitudinally on the table at the will of the chiropractor. For the convenience of the patients .the side handles 79-79 are fixed to the side of the table in the normal position of the patients hands so that he can comfortably adjust-himself to the table.

' Fig. -11 is illustrated means for independent adjustment of the abdominal pads 78 in which the transverse board 81 hinged at 82 to the board 66. This board 81 is provided with the depending bracket '83 in the center of which the spindle 84 is threaded. The end of this spindle is swiveled in the plate 86 on the lowers ide of the board 66, by rotating the crank 87 within convenient reach of the chiropractor, the hinged board 81 may be inclined at any desired angle. i

In Fig. 12, I have shown an alternative means for manipulating the board 66, consisting of a differential slot 88 in the lever 69, engaging a stud 89 in the underside of the board 66 for transforming the ai'cuate movement of the lever into longitudinal movement of the board. In Fig. 11 is shown another alternative means for accomplishing the same purpose consisting of an endless flexible cord attached to the board 66 at 91 and to the lever at 9'2 and passing over the pulleys 93 and 94'respectively attached to the riser 8 and the back'panel 13. i

This disclosure has been confined to a wooden structure embodying the invention, but I do not wish to be understood as confining the invention thereto, because with suitable modifications within mechanical skill it may be adapted to construction in metal and otherwise modified to meet par ticular conditions within the purview of this invention.

Having thus described this invention,

what I claim and desire to secure by Letters- Patent is 2- 1.
